More than 60,000 Delta employees will be sporting the company’s newest uniforms, designed by Zac Posen—some as early as December.

Posen partnered with Delta employees to create the collection, said Ed Bastian, Delta’s CEO.

“I worked alongside employees to understand how they interact with the clothes they wear and developed a look that empowers and excites, because we want Delta’s global workforce to exude the confidence and thoughtfulness that reflects the airline’s brand,” said Posen, who is known for designing couture and high fashion in New York.

It’s been a decade since employees have had a revamped look.

The new uniforms were unveiled in a runway-style event in Atlanta on Tuesday.
